MAHLON HATFIELD, OF MARSHALL, MISSOURI.

BOLT-HOLDER.

SPECIFICATION forming part of Letters Patent No. 300,968, dated June 24,1884.

Application filed February 2, 1884.

' the following is a specification, reference being had therein to theaccompanying drawings, in

which- Figure 1 is a perspective View of the implement; and Fig. 2represents a side view of the same as applied in use.

This invention relates to an improvement in that class of tools employedby blacksmiths, carriage-makers, and other artisans for the purpose ofholding bolts in position, and, by the pressure applied to their heads,preventing them from turning while the nuts are being screwed down, orfor the same purpose when old bolts are to have the nuts removed.

It frequently happens, in making repairs to carriages and farmingimplements, that bolts the nuts of which have become rusted in thethread or otherwise stuck fast have to be removed, and upon applying thewrench to the nut the bolt turns with it. In this case, if the bolt hasa square head, it may be held by another wrench or a pair of blacksmithstongs; but should the head of the bolt be flat or round, as is generallythe case with carriage-bolts, these devices are of no use, as theycannot be applied in such a manner as to prevent the rotation of thebolt. The most practical method of holding the bolt under suchcircumstances yet devised is to bring sufficient pressure upon thebolt-head to cause the frictionbetween it and the surface upon which itbears to exceed the tenacity with which the nut sticks to its threadupon the bolt, thus allowing the nut to be turned while the bolt remainsstationary. To produce a tool that will readily accomplish this resultis the object of this invention.

The method of constructing the implement is as follows:

Referring to the drawings, A represents a bar of metal, preferablysquare or of other polygonal section, one end of this bar, at a, beingdrawn into a wedge or chisel shape and (No model.)

bifurcated. Near this bifurcated end of the bar is a projection or stop,I), which, in connection with the stop I) at the opposite end,

serves to retain upon the bar a slide, B,which is so formed as to movefreely along said bar between the stops. Attached to this slide B by astrong hinge-joint is a bar, 0, the outer extremity of which, oppositethe hinge, is formed into a strong curved and bifurcated hook, c, which,when the tool is in use, may

serve either as a fulcrum for the bar by being hooked over some adjacentpart, or may bear directly upon the bolt-head, while the bifur cated endof the bar A rests against an adjacent part and forms the point ofresistance.

It will be apparent that the slide 13, moving readily to any point alongthe bar A, affords a ready means of adjusting the tool to fit thedifferent situations in which it is used; and, further, that this use isnot limited to holding bolts, as it may be advantageously employed indrawing on wheel-tires and by wagon-makers to draw spokes in place whenputting on the fellies. It will also be found to be a convenient toolfor farmers use in making small repairs, frequently preventing a journeyto the shops to get a troublesome bolt out, and useful for otherpurposes.

Having thus described my invention, I claim asnew and desire to secureby Letters Patent the following:

1. A bolt-holder consisting of a bar having one end chisel-pointed, aslide moving freely on said bar, and a bar hinged to said slide andprovided at its outer extremity with a hook, the parts being arranged toco-operate in the manner and for the purpose set forth.

2. In a bolt-holder, the combination of the bar A, having a bifurcatedand chisel-shaped end, a, and stops 1) and I), with a freely-movingslide B, and bar 0, provided with bifurcated hook c, all the parts beingarranged and operatingas specified.

In testimony whereof I affix my signature in presence of two witnesses.
